Il", are illus- In Figs. 5 and 4.3, l illustrate the application of myinvention to balls instead of rollers, the parts being arranged. to secure the same functions and results as previously described. rthe series ot' balls a7?, tlf. (Z7, are Aheld in. place and loosely connected to the projecting arms d, a", d, of the interior cage or frame D2. and the series ol balls c?, ci, el, are held in place and loosely connected to the inner arms c, c, c, ot the outer cage or ring C2.

As stated the several balls a re loosely connected to their respective arms, and by this I mean that they are permitted sullicient play with respect thereto to allow the selfadjustment previously described. ln other words, in this nmdilieationthe retaining recesses in the arms are of slightly greater diameter than that ot' the balls, and as the dif- -ference mentioned need be very small,v it is shown in Fig. 5 only conventionally.

In Fig. 7, rollers are again shown, but the inner surface A of the part A1 is more steeply inclined than in- Fig. r, and the sur 'face B3 of the partll is coneavely disposed, thus inclining the axes ot the rollers ata yvertical angle 'to each other, instead of their being in a horizontal plane, as before.

In thisform, the rollers, (la, etc., are mounted `*upon projecting spindles do, etc.. on the inner ring D", I'and the'rollers es, etc., upon inwardly projecting'spindles C9, etc., on the outer ring C3, These and many other variations I Aregard as comprised within the spirit of my invention. Thus, the form of 4the easing members or supporting parts, the

number and form of the frames or cages employed, the number of balls or rollers connected thereto, as well as other parts, may be altered and yet still be embraced within my invention. which in its broad terms is the use ot a plurality el sets ot bearing members, each being independent and its members capable 'of selli-iuljustment, lor the purpose previously set Al'ert'h.

ln Figs. l to l'. my invention is shown as applied to a thrust hearing, namely one in which the load is borne longit-.idinally ot the shaft. lt will he obvious, however, that the saine principles are equally applicable to the ordinary radial bearing, wherein the load supported transversely to the shaft. and also to bearings wherein the resistance is both radial and longitudinal: Attention is directed to Fig. i'. as illustrating a bearing oi the class last described wherein due to the angular arrangement ot the elenients. the).y are able to otter resistance not. only to longitudinal thrust but also to some extent to rmlialin'essure as well. It therefore apparent that a mere change in the angle of the members renders the bearing capable ot .supporting both longitudinal and radial pressure and that the natureot the 'thrust depends upon the angle. In other words, the different forms merge into and pass trom one t0 another by linsensible graduations.

My claims therefore are to loe. construed as covering all forms of anti-'Friction bearings,

whether thrust or otherwise., wherein'the same principles o1" operation may be applied` as it will he 'found 1n many instances that the diil'erence between the various types v is not one. ot kind but simply of degree. ln

other words, l desire it to be distinctly understood that l do not limit myself to any specific t'orm or eml'iodiment except in so l'ar as such limitations are; specilied in the claims.

before set `toith, in all o'l the several 'l'orms l have shown tro cages'or frames each provided with three rolling Velements arranged at angles of 1200', this being the pref ed type and the one best adapted to take the thrust and the. internal 'pi ssures as well. and to reduce the number of' i'ia'rts to a -minin'mnt 'lli/ employing a second set of .similar form l double the. carrying capacity olf the liearing and distribute the load between them. Similarly fll obtain the ad- \antagesarising from the capacity `for selfadjustment among the individual rolling ele ments o1 both sets. And still further', l se cure the flexibility proceeding from the possibility of relative adjustment between the two sets,'each taken as a WholeT thus if for any reason one set be accidentally retarded with reference to the other, the opportunity is afforded for relative circumferential adjustment of the sets themselves, apart from and in 'addition to the self-adjustment of los their individual elements before described. Obviously the same advantages will inhere"rv in and increase with-tbe further multipli-- caion ci seis in he seme manner as 'set forth. At iiis point it may be noted sise that theiei's e flecided adantage invoive. in connecting the rolling elements to frames oi1 cages which o contini and hold them in substsntieiiy normai relations and et ine saine time permit che iiniite ssii-adjustment o the individuali elements. Vithout such general eonroiiie elements frequently become dispiece` ami a ioss of efficiency or in some instances the destruction of the bearing iesnis.
